Be it known that. l, WARM): ii). Gmsrn,

a citizen of the United States, residing at Brideton, in the county of{lumberland and tate ot' New Jersey, have invented a new and usefulimprovement in Machines for Making Bottles. Etc., of which the followingis a specification.

rlhis invention relates particularly to Inzichines for making bottles,or similar continuel-5,. which lare provided within the4 mouth-portionwith an iiiiiternel screw thread; and the primary object ot' theinvention is to provide an improved machine for the purpose indica-ted,which is capable of large output, which reduces VWastege to a. minimum,and which isv economicel'in operation.

The invention 'is illustrated, its preferred embodiment, in theaccompanying drawingsa in Whiclimy 'Y 'Figure i represents e broken planView of n, bottle-making machine embodying' the invention; Fig'. 2, e.broken vertical sectional View showing n Jfriction clutch device withwhich the inainlrehpiuions are equipped; Fig. il. n broken elevationalView of the i1nproved uuiehine; Fig. i, a broken vertical sectional Viewtaken at the bu'ble-blowingy station; Fig. 5. a broken plan sectionalView illustrating the manner in which the molds are mounted on theintermittentlyeotuated rotar;7 table; and Fig. il, e vertical sectionalview oi' the mechanism shown in Fig. 5.

lt muy be stated preliminurily that it bottleiuziliing' machine of thegeneral type illustrated is known, such mnehine involv ing' the use of erotary mold-carrier having Y invertible molds mounted on the carrier.The present invention relates part-ieulznrlvvY to the provision et meansin connection with such machine wherebiy bottles having internallythreaded mouth portions may be gu'oduced by ineens of such a. machine.Sei--4 tain ot' the tentures of improvement are adapted, however, foruse in connec-tiim with bOttlemeking mecl'iines generally.

Also, it may be stated preliminerily that in the construction heiteinillustrated the rotery mold-carrer is equipped vwith revoluble.inolihsupports which serve to invert the molds und then right them themolds are carried in their orbit; e pinion-equipped i922. serial no.nettes;

threaded mandrel is carried with esch moldg and a pair ofyieldingly-mounted 65 curved recits are employed for raising endlowering the inendreis;v seristim, one of seid reeks being concave andthe other one being convex, the racks being located on opposite sides otthe path of the pinion's with Whieh eo the mandi-els are equipped. At,the inter mediate' station shown in Fig, l, the glosschurging operationis performed after the mandrel lies been elevated; end et the next'station the bubble-blowing operation is per en formed after the mandrelhas been lowered. s At the intermediate station a blow-head is employedto force the glass down into the lower portion of the mold so that itwill form properly about the threaded tip 'of the 70 mandrel in the neckportion o the mold.

Each, mandrel has a threaded stem which works' through a. nut. which ismounted in coaxial alignment with the mold.

Itv muy be added at this point that the bottle-blanks or psrisons, areformed in the machine illustrated in the accompanying drawings; that themolds are, in the operation ot' the machine, inverted and opened and theparisons or bottle-blanks are transse ferred to e blowing machine; andthat the final operation oi blowing the bottles is performed in themachine last referred to, no illustrationV oi' such machine beingrequired for the purpose of the description of the se inesent.invention.

In the embodiment of the invention illustrat-ed, A 'represents the baseot u treme trom which rises u stationery shaft or col uninlg' B, u'rotary mold-carrier having oe revoluhly mounted thereon a series oi'moldsupports i3upon which ure mounted molds B2; Bn large ire-.ir throughthe medium of which the nioli'l-eurrier i3 is rotated, so that the moldswill he carried in an :.innuler e6 puth or orhit; il sind C' StationeryCanis which serve io close und open the molds; D, e stationerybevel-geur segnn'uit which serves to rotate. the mold supports :indinvert and then right the molds os they'ure carried me through theirorbit.; E, u threaded tubular mandrel nssoeieted with eeeh mold, eachmandrel being; equipped :it its projecting lower end with n geur-elementor pinion ll;

F, :i yieldingly mounted concave rack which m5 serves to elevate themendrels, in turn, es

1 as en axis about which the mold-table B,

actuated by the eear B, turns; and the column A. serves also to supportcertain mechonisms, including the blowfhead which is employed for blowinthe glass down into the mold so'that it wi l form properly about the tipof the mandrel in theneck portion of the mold. The blow-head H employedfor this purpose is of theusnal construction, and operates in the usualmanner.

The mold-table isl given an intermittent or step-by-step n iovement` inany desired manner. The mold-cerrying means comprises the table B andthe series supports B arranged thereon. ech moldsupport comprises ahollow trnnnion or gudgeon l and a disk or iaceplate 1 formed integrallytherewith. The hollow trunnion 1 is jonrneled in a dividedbearing-box 2which is securely fastened to the table B.

Each mold B2 comprises a pair of main mold sections 3 and a pair ofring-mold sections 3, These sections meet in a vertical plane and areprovided with arms 3b and 3,respectively, which are connected ai theirinner ends with a `pivot Al carried by lugs 4 which project from thefaceplate 1". Thus, the mold sections are capable ggf separating at aplane containing the axi of the mold.

The threaded mandrel or plonger E, associated with each mold, works in anut 5 which is rigidly secured to a bracket 5, the bracket 5'" beingrigidly mounted on the faceplate oi l the mold-sn port B. The bracket 5comfprises a tabu ar member 5l carried by a shank 5: and a pair ofstrong studs 'or bolts 5d which project. `from the face-plate of 4themold-support B1. The .shank 5 of the hrm-kel is equipped with loops orrings 5 which are mounted on the laterally projecting studs 5d.Thetubnlor portion 5" of the bracket is thus stannchly supported on thestuds 5* and may be adjusted thereolniif desired. Any suitable seem-imgrmeans` (not shown) may be e ploycd. The tubular por- Y tion 5" of thebracket is. located directly below the mold and is provided at its upperportion with o. peripheral flange 5f which interlocks with dances withwhich the ring-sections 3'* of the mold are provided. The not 5 has aportion which progects into the tubolari' pass into the chamber 6 duringthe bubble of mold! member 5* and secured by bolts (not shown) to thetubular member 5b.

Above the not 5 is a space or chamber 6. The mandrel E extends throughthis chamber. It has a tip portion T which is provided with a thread Twhich serves to form a thread within the mouth of the bottle. The tipportion of the mandrel has a reduced tubular shank within the Yhollowshaft which forms the mainv shonlr 7 of the mandrel. The shank 7 isexternally threaded-and engages the nut 5. The pitch of the thread onthe shank 7 corresponds with the pitch of the thread 7 at the `tip ofthe mandrel. The hollow mandrel ti 7 is provided withlaterallyopenmgorltic'es 7d adapted to permitan to blowing operationlThe opper portion o the threaded shank is provided with a lateral stud 8which is adapted to engage an inwardly-projecting stud il which extendsinto the upper portion of the chamber 6, and.l thus limit the upwardmovement of the mandrel. gage a 'stud l0 which. projects upwardly fromthe nut 5, and thus limit the downward movement of the mandrel.;

The pinion E of each mandrel E is frichas a flange 5g which l which isfitted securely The stud 8 is also adapted to en-k tionally mounted onthe lower end of the mandrel-shank 7", as will be clearly onderstoodfrom Fig. 2. 1 The purpose is to pern mit the pinion to slip or turnwith r lation to the mandrel after the mandrel has been raised orlowered 'by the rech. ln the'illnstration given, the shank 'if or eachmandrel is provided wlth a reduced lower end portion l1 encircled bysections ll"M of a cone winch engage the interior/conical surface il oi'the Lpinion E. The cone-sections 1l are vieldingly held in grippingposition by a ci coil springll whi is interposed between the conesections and a not lid which is mounted on the reduced end'll oftheshank of the mandrel. ln practice7 the racks are made somewhat longerthan would be ref quired to elevateor lower theumandrels, .and provisionfor slippage of thepinions, that is,

rotation ofy the pmions without further movement of the `nnmdrels7 ismade. The

friction deviceshown answers-the purpose admirably, but .anyothersnitable connection The rac is are preferably mounted onyieldinglyfheld.. bel -cranli members., The

purpose is to permlt ay suihcient yielding of the rack to insure thepinion. comingv properly avoidingr in case the end stril-ze the Aend'ofa tooth ofv the gear-segment or rack.

The bell-.crank members i2 yfurther have vertical pivotportions l2 jourried by the standard orl bracket 13, end ere equippedwith nuts l2 which serveto iidjust the' tension of springs l5 which ureconfined between the lugs 1li and the arms The chamber 6 shown in 12".Thus the springs l5 serve to hold the reclrF yieldingly'in the positionshown in Fig. l.

In a similar manner, bell-crank members 16, equipped with springs 16,serve to hold the rack Ff yieldin y in the positionI shown in Fig. l.The be l-creiilr members 16 are mounted on-a bracket or standard 17carried by the base of the frame.

As will be understood from Figs. l, 5 and, 6, the mold seetionsv areopened and closed through the medium of a plunger 18 which extendsthrough the hollov7 truniiion l. oi the mold support, the other end or"the plunger being connected', by links 19, with the mold sections. Eachplunger 18 isequpped et its inner' or rear end with e oem roller idg;-end the movements of the plunger :ire controlled bythe cams C and Cshown in Fig. l.

On the hollow trunnion l of each mold 'support is secured a bevel gear20. v'lheee bearing-box may be .suoli es to cause the' bearing-box to rithe trunnion of the inold-support su eiently to maintain the mold iiiits upright position during the pessege of the mold from one station tosiiother. Any suitable looking devices may be employed for releasablylooking tlie inolds in upright position,4 so that tney will be properlymaintained in such position during their travel in the upright position.

ig. l communi- Cates through e central 'passage 6 with the neck portionof the mold cavity.. Thus when the mandrel is retracted air mayA passfrom the bubble-blower into the cavity in the glass and blow the glassto Complete psrisoii form. The bubble bloiv-heed G shown in Fig.

4- eomprises a pipe 2l equipped with s veial tit-el hoe( on which isswiveled e ver tical tip A depending stem 24; carries the device G, thisstem being equipped with a piston :35 Working in e cylinder 26. The

blow-heed G is elevated by pneumatic pressure. The blovvdiesd risesabove the position shown in Fig. and is then depressedv by the mandrel,the tip portion 23 oi the device rotating with the mandrel.

tion is permitted by a ball hearing The pneumatic pressure which raisesthe pistou' This sc- 25 is suiioiently light to enable the blow-'1* headto be depressed by the mandrel, esthe' f mandrel descends,'until thestud 8 engeges the stop i0. The portion S21-3 of the device G isprovided with n bevel tip 28 .vl'iieh is adapted to engage e. conicalrecess 28 with which the tubular mandrel shank is pro` vided et itslower end as shown in Fig. 2. l'

The operation of the improved machine may be stated brieiiy iis follows:

The mold-table B is given an intermite tent movement of rotation in theusuelv manner, the rotation being effected through the medium of thelarge gear B3. Asthe molds are carried pest the concave rock l?, themandrel pinions travel along the ruck and cause the meudrels to beelevated. Thus, the niendrels occupy the elevated poA sition when they-reecli toe. glasschargingl station, which is the intermediate stationvAt this point, the operzishown in Fig. l. tion of introducing theinetelf oir-molten glass, is performed, e funnel if being' em-` i;desired to facilitate this opere-A 'llie gloss is severed by ineens ofsi,
